I am trying to find out if a design of a residential battery operated AC power source (similar to a UPS) is by the NEC code or if not, how to get it to be code compliant.
The power source requires access to power coming from a renewable energy source - not Gridtie. The line has to run AC from the inside to the outside to a small unit that sits on the ground under some solar panels/turbines/etc. As a variation the line from inside to outside could be also carry DC.
What doe the NEC codes say about this power line and setup, pro & cons, any experience ?
